This paper presents the results of a function-based study initiated by a general education teacher to reduce a general education student's out-of-seat behavior. Procedures included direct observation, data collection, functional behavior assessment using a Functional Assessment Protocol (FAP; Schroeder, n.d.), hypothesis development, and creating…

This study aims to be a contribution to a theoretical model that explains the effectiveness of the learning and decision-making processes by means of a feedback and mental models perspective. With appropriate mental models, managers should be able to improve their capacity to deal with dynamically complex contexts, in order to achieve long-term…

College students seem especially adept at procrastination. Large percents report that it causes lower quality papers and projects, lower exam scores and, to a lesser extent, late or missing assignments. Using survey data collected from a broad cross-section of students and faculty we argue that procrastination can be modeled as a logical, albeit…

Genre analysis, the investigation of typified communicative actions arising in recurrent situations, has been developed to study information use and interchange online, in businesses and in other organizations. As such, it holds out promise for the investigation of similarly typified communicative actions and situations in CSCL contexts. This…

Changes in the family structure can be very disruptive to adolescents who live in those families. This article examines the impact of the number of family transitions on delinquent and drug-using behavior. Specifically, the effect of family transitions is hypothesized to be mediated by problems within the family, school, and peer settings. A…

Cytochrome P450 enzymes are a family of heme-containing proteins located throughout the body with roles in metabolism of endogenous and exogenous compounds. Among exogenous compounds, clinically relevant pharmaceutical agents are nearly all metabolized by P450 enzymes. However, the activity of the different cytochrome P450 enzymes varies among…

This article examines the acquisition of Korean imperfective markers, the progressive "-ko iss-" and the resultative "-a iss-," with a view to understanding how tense/aspect morphology expands beyond prototype associations with inherent aspects of the verbs. We hypothesized that "-a iss-" will develop later than "-ko iss-," but that the…

Recent research on executive function (EF) deficits in autism has led investigators to conclude that EF deficits are secondary to the disorder. The current study has two major goals: (1) Examine whether specific EF deficits are present in the youngest autism group to date (mean = 22.9 years), and (2) examine whether such deficits are secondary to…

Many theories of category learning assume that learning is driven by a need to minimize classification error. When there is no classification error, therefore, learning of individual features should be negligible. The authors tested this hypothesis by conducting three category-learning experiments adapted from an associative learning blocking…

This article provides researchers with a guide to properly construe and conduct analyses of conditional indirect effects, commonly known as moderated mediation effects. We disentangle conflicting definitions of moderated mediation and describe approaches for estimating and testing a variety of hypotheses involving conditional indirect effects. We…

The paper presents a characterisation about argumentation and proof in mathematics. On the basis of contemporary linguistic theories, the hypothesis that proof is a special case of argumentation is put forward and Toulmin's model is proposed as a methodological tool to compare them. This model can be used to detect and analyse the structure of an…

Comments on the original article "A New Big Five: Fundamental Principles for an Integrative Science of Personality," by Dan P. McAdams and Jennifer L. Pals (see record 2006-03947-002). In presenting their view of personality science, McAdams and Pals (April 2006) elaborated the importance of five principles for building an integrated science of…

Two-alternative, forced-choice tests are commonly used to assess cooperation in examinations of neurocognitive functioning. Most commercially available tests do not primarily depend on comparing the total correct responses to the number expected by guessing. Nevertheless, the tests afford an opportunity to make stronger judgments about the…

This paper describes the confirmatory factor analysis, validity, and reliability data collection stage of the development of a scale to measure mainstream teachers' self-efficacy beliefs for teaching ELL (English Language Learner) students. Data were collected from 708 K through 12 teachers and pre-service teachers with varying degrees of…

An illustration of a test for independence was provided with a mixed set of variables. The matrix consisted of 10 tests of interest and four random deviates in which the relationship between sets was demonstrated to be minimal. The result was discussed for a situation in which factoring methods might be considered. (Author)
